export default defineConfig({
  plugins: [vue()],
  resolve: {
    alias: {
      '@': fileURLToPath(new URL('./src', import.meta.url))
    }
  },
  server: {
    host: '0.0.0.0',
    port: 80,
    open: true
  },
  css: {
    preprocessorOptions: {
      scss: {
        additionalData: `@import './src/global.scss';` // `@mixin cover(){background: blue;}`
      }
    }
  }
})
